MECHANICAL DRIVER.

SPECIFICATION forming part of Letters Patent No. 645,280, dated March 13, 1900. Application filed my 31,1399. Serial No. 725,713. (No model.)

To all whom, it may concern.-

Be it known that I, INGLIs M. UPPEROU, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented certain Improvements in Mechanical Drivers, of which the following is a specification.

This invention relates to the class of devices used for transmitting rotary motion and power; and it has for one'object to provide a simple mechanism whereby the rotary motion of a motor may be transmitted to any machine to be drivenas a printing or sewing machine, for example- Another object of the invention is to provide a simple means for transmitting from the uniformly-rotating driving-wheel a rotary motion at different rates of speed within limits as may be desired.

The device is particularly adapted to theuse of electricity; but other motive power may be employed.

In the accompanying drawings, which illustrate an embodiment of my invention, Figure 1 is a plan of the invention, showing also the wheel of a machine to be driven thereby. The dotted lines show the driving mechanism out of action and the full lines show it in driving position. Fig. 2 is a plan of the carriage of my mechanical driver andthe base of the motor, the motor being omitted. Fig. 3 is a side elevation of my mechanical driver as seen from the side opposite the driven wheel 3 in Fig. 1. Fig. 4 is a view showing a modification.

Referring to the drawings, X represents any suitable support, as a table or bench, and Y in Fig. 1 any machine to be driven, said machine having a driving-wheel 1], provided with a tire or rim y, of rubber or other suitable material. I

Secured firmly to the table X is a base-piece or bed 1, and the machine Y may also be secured thereto. On the base-piece 1 is rotatively mounted at 2 a carriage or carryingplate 3. As shown in the drawings at Fig. 1, the carriage 3 rotates or turns in a horizontal plane; but this is not material. The carriage 3 is provided with a suitable handle at for moving it and has mounted on it an electric motor 5, inclosed in a suitable casing. The

'tained momentum.

motor has a projectingarbor 6, on which is secured a cone-shaped driving-wheel 6, so it may be brought into driving contact with the rim or periphery of the wheel y of the machine to be driven by turning the carriage 3 about its center of rotation 2, as indicated in Fig. 1. The'arbor or shaft 6 is longitudinally fixed and journaled at 6 on opposite sides of the motor-casing. The motor being connected up with the conductors of a circuit suppliedby a suitable generator through the wires w, rotary motion will be imparted to thecone-shaped driving-wheel 6. This motion will be transmitted to the wheel y when the cone-shaped driving-wheel is brought in contact with it. Where electricity is used as a motive power, it is advisable to start the cone-wheel 6 while free from the wheel 7 and notrequire any work from it until it has ob- By then operating the handle 1 the drivingwheel is brought into operative contact, as shown in Fig. 1, with the wheel y and the machine set in motion.

The motor 5 may be rotatively mounted on the carriage 3, the axis about which it rotates being indicated by a in Figs. 1 and 3. This axis is at right angles to the axis of rotation of the cone-shaped driving-wheel 6. As shown in Figs. 1 and 2, the axis of rotation of the driving-cone is horizontal and that of the motor is perpendicular thereto or vertical. The motor 5 has a foot or base 5 which has in it a concentric limiting-slot 5 engaged by a screw or stud 3, which is set in the carriage 3. This foot or base 5, which carries the motor, has also on its under side apin 5, to which is secured one end of a spring 7, the other end of said spring being attached to a pin 7 in the under side of the carriage 3. Thus when the driver is turned to the position indicated by full lines in Fig. 1 and the driving-cone 6 is brought to bear near its lesser end upon the rim or periphery of the wheel y it is held up to the wheel by the elastic tension of the spring 7, and if it is desired to drive the wheel y with greater speed the carriage 3 is turned by moving the handle 4 still farther in the direction of the arrowocin Fig. 1, and this has the effect of forcing the driver-cone 6 against the rim y and at the same time moving it in the direction of the axis across the face of the wheel y, so as to make the point of contact between the driverand wheel where the diameter of the cone is greater. Fig. 1 shows the relative positions of the driver and the wheel whereby this result may be obtained. The foot or base 5 has a projecting socket-piece 5, in which a connecting-collar is socketed. Through the center of the connecting-collar 0 a bolt passes. The head of the bolt is on the interior of the casing of the motor 5,and a nut 10 below the collar securesit to the motor-casing. The carriage 3 has on its upper face a circular projecting rim 3, which projects up through an opening in the base 5 and provides for the rotation of the base 5.

The collar 9 is held in place bya set-screw 9'. The wires'w to pass up into the motorcasing through the'hole in the collar alongside-of the bolt 10.

As the face of the cone travels across the Wheel y and the circumference of the drivingwheel in contact increases the motor-base 5 will rotate on its axis and distend the spring 7. The pressure of the d riving-wheel is there by increased and the speed of the driven wheel accelerated.

In order to secure the driver in position when the cone 6 is in contact with the wheel or periphery of the wheel to be driven, the handle 4 has a screw-threaded shank 4,which I screws through a socket on the carriage 3 and may be'made to bear forcibly as a brake on the bed 1 and hold the drivingcone-wheelup in position on the rimy. The movement of the carriage 3 about the point 2 may be limited by a slot 8 and pin, as indicated in dotted lines at 2 in Figs.-1 and 2. It is preferred to employ an electric motor with the driver; but I do not wish'to confine myself to this particular motive power, as other sources of power may be used and anyform of motor capable of effecting the object may be employed. Although I prefer 'the arrangement of parts shown in Figs. 1, 2, and 3, the invention is not limited to the construction therein shown, as this may be materially varied without departing from my invention. For example,the driver would produce good results if the driv ing-wheel 6, Fig. 1, were cylindrical instead of. conical; but no increased speed would be obtained therewith unless the wheel of the machine were made conical, as shown in the modification, Fig. 4, and the motor may be approached to the machine to be-driven in various ways. Y r

In Fig. 4 a modification is shown in which the base 5 carrying the motor with the driving-wheel, is arranged on ways 9 9 and a threaded screw 10 and wheel 11 substituted for the handle 4. 'In such modification the driving-wheel 6 is also shown with a plain tire, and the wheel Y attached to the machine, is made cone shaped. In such arrangement the speed at which the machine is driven depends upon the position of the driving-wheel on the cone.

' said motor,

In the drawing'Fig. 4 the pivotal center 7 on which the motor 5 moves is shown in dot-- ted lines. The spring 7, Fig. 3, used to hold the driving-wheels of the motor in frictional I contact with the driven wheel, is on the unto secure by Letters Patent, is-
